In what scenarios would it be more appropriate to use memory_get_usage(false) instead of memory_get_usage(true) for accurate memory usage measurement in PHP scripts?

When measuring memory usage in PHP scripts, it is more appropriate to use memory_get_usage(false) when you want to get the memory usage of the current script without including the memory allocated for variables that are not being used. This can provide a more accurate measurement of the memory actually being utilized by the script itself.

// Get memory usage of the current script without including memory allocated for unused variables
$memoryUsage = memory_get_usage(false);
echo "Memory Usage: " . $memoryUsage . " bytes";
